14 Herculis c is an extrasolar planet approximately 59 light-years away in the constellation of Hercules. The planet was found orbiting the star 14 Herculis, with a mass that would likely make the planet a Gas Giant roughly the same size as Jupiter but much more massive. This planet was discovered on November 17, 2005 and published on November 2, 2006. [cite journal |url=http://cdsads.u-strasbg.fr/cgi-bin/nph-bib_query?2006ApJ...645..688G&db_key=AST&nosetcookie=1 |author=Goździewski, K., Konacki, M., Maciejewski, A.

It may be in a 4:1 resonance with the inner planet 14 Herculis b.
